Chicco KidFit Zip Air Plus 2-in-1

The Chicco KidFit Plus Zip Air is a high performing highback-to-backless booster that provides very good belt fit in either mode. The seat also offers an optional footrest for additional comfort, meaning (potentially) less slouching and wiggling in the seat for a better seatbelt fit. The zip cover makes for easy removal and cleaning.

While this model can be used with or without its seatback, CR recommends highback boosters for everyday use because they typically position the shoulder belt better on a child, provide some side-impact protection, and offer a more comfortable place for resting children to lay their head. Once your child outgrows their forward-facing child car seat by weight or height, CR and the American Academy of Pediatrics (AAP) recommend that kids use boosters until they are at least 4 feet 9 inches tall, are 8 to 12 years old, and have the developmental maturity to keep their belt properly positioned for an entire car ride.
